Vortex and Nikon both made scopes of the 3-12x42 variety with side focus (parallax) adjustment and with a BDC reticle. The BDC is my preference for hunting because I can't read the etching on a turret w/o glasses and can't shoot with them. Both Vortex and Nikon have apparently quit making scopes with side parallax adjustment and all the mfgs seem to be going to high end magnifications that are unsuitable for hunting. Anybody know what is going on here?
